AIR MAIL

Where today’s air came from

The air arriving over Johnson about 5,000 feet above the ground was over the open Pacific three days ago, and over the Canadian Prairies a day ago, about 2,710 miles back along its path. It came down from about 12,400 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THE GROUND

What Johnson stands on

Johnson’s center stands about 1,160 ft above sea level. Within three miles the land runs from 1,160 ft to 1,190 ft, a difference of 30 ft: nearly flat ground.

Under the town center the state geologic map shows Biotite schist of graywacke protolith, and schist-rich migmatite (biotite-schist, migmatite), from the Neoarchean, 2.5 to 2.8 billion years old.

The section below crosses 4 rock units mapped at the surface.

Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Rock at the surface along the line

Undifferentiated

Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 9 mi of the line.

Metabasalt, greenstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 7 mi of the line.

Biotite schist of graywacke protolith, and schist-rich migmatite

Biotite-schist, migmatite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.

Granitoid intrusion

Granitic. Age: Neoarchean, 2.5 to 2.8 billion years old. About 3 mi of the line.

From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

THE WATER

Where Johnson’s rain goes

A raindrop that lands in Johnson reaches Hudson Bay by way of the Lost, the Clearwater, the Red Lake, the Red River of the North and the Nelson: about 1,090 river miles. Past the border it runs north through Canada to Hudson Bay.

THE WAY DOWN, TO SCALE
Johnson≈ 1,090 mi · Hudson Bay
FROM THE CENTER OF JOHNSON ≈ 1,090 mi to Hudson Bay Lost → Clearwater → Red Lake → Red River of the North → Nelson

Lake on the way: Lake Winnipeg.

400 miles of the trip are on the Nelson.

Traced down the USGS NHDPlus V2.1 river network from the Census center point of Johnson; river miles along the main stem, rounded.
